Log: Merge the md_page structs for AIM and Book-E into a single unioned struct Summary: Ports like sysutils/lsof troll through kernel structures, and therefore include kernel headers and all the dirty secrets involved. struct vm_page includes the struct md_page inline, which currently is only defined if AIM or BOOKE is defined. Thus, by default, sysutils/lsof cannot build, due to the struct md_page having an incomplete type. Fix this by merging the two struct definitions into an anonymous struct-union. A similar change could be made to unify the pmap structures as well.
